Marta Tachibana (立華 マルタ Tachibana Maruta) is a secondary character of Dance With Devils. She was the lover of Lord Nesta, the sister of Maria Tachibana, the mother of Lindo Tachibana and the aunt of Ritsuka Tachibana. She died before the beginning of the series. Marta bore extreme resemblance with her son Lindo Tachibana. She had short red hair, turquoise eyes and was fair skinned, she also wore a purple lipstick. She wore a gray blouse, white pants and white heeled shoes. Before dying, Marta became skinny and pale, looking more like a skeleton than a human. Before giving birth to Lindo, Marta seemed to be rather a smiling and responsible woman. However, she was shown to be reckless and have a complete disregard for the rules in pursuing a relationship with Lord Nesta the Vampire Lord. Once she gave birth to Lindo who was a dhampir, she 'died' from the inside and became quiet, refusing to see him as her son and saying that hers was dead, devoured by a monster. According to Nesta, Marta was like the moon, cold and gray, and while she loved her sister, Maria Tachibana she also resented her, probably due to Maria being loved by all.

Dance with Devils
Ritsuka Tachibana has always been a good student, so she is completely shocked when she is suddenly summoned by the student council. Even more, they seem to think of Ritsuka as a troublemaker. Led by the handsome Rem Kaginuki, the student council—also consisting of Urie Sogami, Shiki Natsumizaka and Mage Nanashiro—tries to question her, but it soon becomes clear that they have ulterior motives. However, this is only the beginning. When her mother gets kidnapped, her life is turned upside down, and Ritsuka gets drawn into a world of vampires and devils. Both groups are searching for the "Grimoire," a forbidden item allowing its owner to rule the world. The return of her brother Lindo from overseas gives her hope, but even he appears to be hiding something. In a world filled with secrets, Ritsuka questions whom she can trust in this dark musical tale, while the handsome and dangerous members of the student council compete for her attention.
